GEORGE EDWARD MORRIS, OF REGINA, SASKATCHEWAN, CANADA.

BEADING IMPLEMENT.

To all whom it may concern:

Be it known that I, GEORGE EDWARD MORRIS, a subject of the King of Great Britain, residing at Regina, in the Province of Saskatchewan, Canada, have invented certain new and useful Improvements in Beading Implements; and I do hereby declare that the following is a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to tube expanding and beading tools.

The object of my invention is to provide a tool which will properly expand the end of a tube and form a bead thereon in one movement, and which will be rotated by the oper ation of an imp acting element.

A more specific object is to provide a pivot ally mounted supporting plate with a rotatable head carrying a suitable tool; and, further, to provide means on the head for normally maintaining the tool in raised position in the path of movement of the impacting element, and for guiding the tool so that the tube operated on is expanded by a blow almost at right angles to the plate to which the tube is being attached. The advantage sought to be attained by this construction is that more or less unskilled operators may use the tool and produce proper work.

A further object is to provide means for slidably supporting a base plate, so that the tool may be adjusted to the work.

My invention consists of the construction, combination and arrangement of parts, as herein illustrated, described and claimed.

In the accompanying drawings, forming part of this application, Ihave illustrated one form of embodiment of my invention, in

which drawings similar reference characters designate corresponding parts, and in which:

Figure 1 is a side elevation, partly broken away to show the construction, and showing the application of the tool to a boiler tube; Fig. 2 is a plan view of the tool, with the hammer arm broken away Fig. 3 is a vertical section through the head; and, Fig. 4 is a perspective of the beading and expanding tool.

Referring to the drawings, 1 designates a base plate provided with a longitudinal slot 2,

having inwardly inclined side walls. A twopart holding member 3 is provided with anges 4, coinciding in shape and dis osed to bear against the inclined side walls 0 the slot 2. A taper bolt 5 is disposed vertically through the holding member 3, and has a lock nut 6 on its upper end, so that the hold ing member 3 may be expanded to lock the same in the slot 2. The holding member 3 may be attached in any suitable way to any common form of support, and forms the base supporting means.

The base plate 1 is provided on its forward end with bearing shoulders 7, between which shoulders is pivoted a su porting plate 8, which projects beyond the orward end of the implement, and which rojects to the rear end of the implement an is provided with an ofiset rear end 9. A coiled spring 10 is disposed under the rear end of the supporting plate 8, and is adapted to normally maintain the rear end thereof elevated, but is further adapted to be compressed to take 11 the shock on the forward end of the plate, ue to the operation of the implement. The spring 10 is maintained in position by means of a stud 11 on the base plate 1. The forward end of the supporting plate 8 is provided with' an expanded portion 12, through which is disposed a rotatable removable head 13 of a size to work into a tube 14.

The upper end of the head 13 is provided with a squared shoulder 15, to which is secured an actuating ratchet 16. The ratchet is preferably secured to the head so as to be easily removable by having in the ratchet an opening 17 of a shape coinciding to the shoulder 15 of the head, so that screws 18 will hold the parts together. The head 13 is maintained against upward vertical movement, but is left free to rotate with relation to the supporting plate 8 by means of pins 19 disposed transversely therethrough and workmg against the under surface of the supporting plate 8.

A locking pawl 20 is pivoted on the supporting plate 8 in a position to engage the ratchet 16 to prevent reverse movement of the head 13. A suitable spring 21 has one end connected to the pawl 20 so as to maintain it in engagement with the ratchet, and has its opposite end secured to the forward end of a reciprocable actuating pawl 22, which is adapted to engage the ratchet 16 to cause rotation thereof in one direction. The spring 21 therefore performs a double func tion in maintaining the pawl 20 in engagement with the ratchet 16, and in maintaining the actuating pawl 22 normally out of engagement with the ratchet 16 in its retracted position. i

The actuating pawl 22 is disposed on the upper surface of the supporting plate 8, and is reciprocably mounted by means of pins or screws 23 disposed through slots 24 therein, and working into the supporting plate 8. The rear end of the actuating pawl 22 is bent downward as at 25, and extends in the path of movement of a shoulder 26 formed on a hub 27, which hub 27 is rockably supported between shoulders 28 formed integral with the su porting base plate 1 at its rear end. Carrier by the hub 27 is a bent arm 29, carrying a hammer or impacting element 30. This arm 29 may be operated by any suitable mechanism, and when it is operated to rock the hub 27 on its pivotal support, the shoulder 26 works against the rear end of the actuating pawl 22, and causes its forward end to engage the ratchet 16 to cause'rotation thereof in the direction indicated by the arrow in Fig. 2.

A rectangular tool 31 is reciprocably disposed in a slot 32 formed in one side of the rotatable head 13. The slot 32 is provided with a rear inclined guide wall 33. The tool 31 being forced downward, rides on the guide wall 33, so that the movement of the outer end of the tube is almost at a right angle to the plate or sheet of metal to which the tube is eing attached. Guide flanges 34 are formed on the sides of the tool 31, and work behind or inside of guide lugs 35 formed on the side walls of the slot 32, and this construction forms a retaining means for the tool 31.

The rotatable head 13 is provided with a recess 36 extending inward from the inclined guide face 33,and seated in said recess is a spring 37, the upper end of which thrusts into a recess 38 formed in the inner face of the tool 31, and serves as a means for normally maintaining the tool 31 in elevated position, in the path of movement of the im pacting element 30. Extending from the front face of the tool 31, is a hooked beading lug 39, and from the beading lug 39 to the lower end of the tool there is formed a curved expanding face 40, so that the impact against the upper end of the tool is directed directly against the tube at a point opposite the edge of the opening through the plate 42 to which the tube is being attached. The upper end of the tool 31 is provided with anoffset head 41, so that the full force of the impact may be directly transmitted as described.
